Upgrading the System Hardware
Warning
Before attempting any upgrade to the Vario L2 computer, please read the section "Precautions". For your
personal safety it is important that you ensure that the unit is switched off, and the DC supply is disconnected.
Remember that the unit incorporates an ATX-type of power supply unit. Switching the power off using the front
panel switch does not isolate the DC supply, and under these conditions the +5V DC standby power is still
connected to the motherboard.
For the safety of the equipment, it is important that you observe electrostatic discharge precautions. Do not
remove new items from their anti-static bags until necessary.
When making any internal changes to the computer, it is imperative that the internal cables follow the original
routes and additional cables are installed as described. Failure to observe this requirement could restrict the
airflow through the unit and cause overheating problems.
Upgrade Options
The user may upgrade the unit by adding more memory or a faster CPU to the unit. Before upgrading, please
check with Blue Chip Technical support by emailing [e-mail] to find out if your
proposed upgrade is supported.
PCI Options
The unit incorporates only a 120W Pico Power Supply. As such, great care should be used if trying to select and
fit a PCI adapter card, as there may not be enough system power available to allow it to operate reliably
Please contact Blue Chip Technology Technical support at the above email address to discuss your proposed
addition.
